Hello. I have a strain that I have been keeping for about a year by cutting clones every time I run a batch. I have been dealing with PM ever since I started, and I do not know if the babies had them originally, or if they were infected in my garden. I have since fixed my indoor garden's environment to be as non-conducive to mold as possible (2 a/cs, 8 fans-2 on each side of room, plus 4 fans on the lights and 1 more on a can), but, I still get it. Recently I had it in the beginning of my last run, but I killed it with ONE application of Serenade spray (I KNOW!!! I LOVE the stuff!!!!) So, on to my question. I have cut more babies, and they have been in the box now for about 2 weeks. I use rockwool and a dome, in a plywood box I made with 2 fluorescent 18 inch lamps above the dome. I usually have about a 70-80% success rate. This time, I did a WHOLE thing of cubes, so, Im wondering if the mold came from 1)too much moisture and not lifting the dome lid enough because of all the cubes. Usually I only do about 20-30 at a time, or 2)Is the mold systemic, and it keeps appearing because it was in the mother plant, and conditions in the clone box are allowing it to resurface. And, can I spray the babies with serenade, or do I have to wait until they get bigger and just hope they can push through a little longer?
